TLV271CDRG4 is a low-voltage, rail-to-rail output, single-supply operational amplifier in an 8-pin micro-DIP package. It is perfect for many analog applications, such as instrumentation, data conversion and active filtering. The TLV271CDRG4 is ideal for applications where space is limited and the need for high accuracy, low power, small size and wide bandwidth is essential.

Application Field

The TLV271CDRG4 is an excellent choice for instrumentation and data conversion applications such as:

• Analog-to-Digital (ADC) Converter
• Digital-to-Analog (DAC) Converter
• Amplifier/Buffer
• Filter
• Instrumentation Amplifier
• Data Acquisition
• ADC/DAC Interface
• Sensors

The TLV271CDRG4 can also be used in digital signal processing (DSP) scenarios, such as in pulse-width and frequency-modulated (FM) applications.

Working Principle

The TLV271CDRG4 is designed as an operational amplifier in an 8-pin micro-DIP package, with a +2 V to +12 V single-supply operation and rail-to-rail input and output. The integrated amplifier is made using BiCMOS process, using high-performance transistors, and offers a wide frequency bandwidth, a wide rail-to-rail input common-mode range, rail-to-rail output swing and low input bias current. It operates in open loop, with a voltage gain (AOL) greater than 10 V/V.An input differential amplifier stage is followed by a high frequency, current-mode stage and an output voltage amplifier. The TLV271CDRG4 is ideal for high voltage applications where smaller package size and fewer components are essential. The TLV271CDRG4 features high output drive and flat frequency response, with fast settling time and low distortion. It operates from a single +2 V to +12 V supply and draws only 1 μA of supply current. The TLV271CDRG4 can support high power levels up to +8 dBm in the 500 kHz to >100 kHz range, with a unity-gain slew-rate of 0.9 V/μs.

The TLV271CDRG4 is ideal for a variety of analog applications, including active filters, data converters, and instrumentation amplifiers. It also performs well in digital signal processing (DSP) scenarios, such as in pulse-width and frequency modulation (FM) applications. The amplifier is designed to operate in single-supply mode, with a wide common-mode input range unprecedented in a single-supply amplifier. The output swing is also adjustable and rail-to-rail, which makes it a perfect solution for many digital applications. Additionally, its low-power operation mode, high-impedance inputs, rail-to-rail outputs and wide common-mode input range make it an ideal candidate for use as a low-voltage analog-to-digital (ADC)/digital-to-analog (DAC) converter interface.

Conclusion

The TLV271CDRG4 low-voltage & single-supply rail-to-rail output operational amplifier offers a wide frequency bandwidth, rail-to-rail input common-mode range and rail-to-rail outputs, as well as high output drive, low input bias current and low distortion. It is an ideal choice for instrumentation and data-conversion applications such as active filters, data converters and instrumentation amplifiers. The TLV271CDRG4 is also well-suited for a variety of digital signal processing (DSP) tasks such as pulse-width or frequency modulation (FM) applications, and its adjustable rail-to-rail output makes it a perfect choice for low-voltage ADC/DAC converters.
